[Feature Request] Support BoxPlot Chart

[markmssd]

Feature request summary

A Box Plot is useful to show distribution of one of more points of data. Here's a good explanation of it: https://www.atlassian.com/data/charts/box-plot-complete-guide#:~:text=A%20box%20plot%20(aka%20box,line%20marking%20the%20median%20value.

I am still unsure of the best API to use it. Should each data group be an array of points, and the lib calculates the median, quartiles, min, and max, or should the user precalculate the and provide them 🤔

This kind of chart will have a different type than the others. It would have a key, but the value would be more complex:

{
  key: number | string;
  value: {
    median: number;
    lowerQuartilze: number;
    upperQuartilze: number;
    min?: number;
    max?: number;
  }
}

or

{
  key: number | string;
  value: DataPoint[];
  metadata: {
    hideMinMax?: boolean;
  }
}

I think the second way is better, because D3 already provides methods to calculate median and quartiles.

Either way, we should make the min/max optional

Rationale

There is currently no way with Polariz for Box Plot charts. If that makes sense, I am willing to open a PR for it.
